Fast track surgery for children with congenital pseudarthrosis of the tibia: A prospective interventional study.

OBJECTIVE: The purpose of this study was to explore the effect of fast-track surgery combined with a clinical nursing pathway on the recovery and complications of congenital pseudarthrosis of tibia. METHODS: 82 children with congenital pseudarthrosis of tibia admitted from January 2019 to December 2020 were selected as the study subjects. The control group received routine clinical nursing pathway while the intervention group received a fast-track surgery combined with a clinical nursing pathway. The fasting and water deprivation time were arranged according to the pre operation time, and the accelerated rehabilitation nursing models such as progressive diet management, multi-functional analgesia, and early sequential functional exercise were given after the operation. After collecting data on perioperative diet, postoperative recovery, postoperative complications, and family satisfaction from both groups of patients in a large hospital in China, a comparative analysis was conducted. RESULTS: The retention time of negative pressure drainage tube, urinary catheter and hospital stay in the intervention group were shorter than those in the control group (P < 0.05); The incidence of complications in the intervention group (5%) was significantly lower than that in the control group (21.42%) (P = 0.029). The family satisfaction of the intervention group (95.00%) was higher than that of the control group (80.95%). CONCLUSION: Strengthening the concept of fast-track surgery nursing in the combined operation of congenital pseudarthrosis of tibia can shorten the hospitalization time of children, reduce the occurrence of postoperative complications and improve their family satisfaction.

Application of the "telescopic rod" in a combined surgical technique for the treatment of congenital pseudarthrosis of the tibia in children.

BACKGROUND: The current surgical treatment of choice is the combination surgical technique, involving tibial intramedullary fixation to maintain the mechanical axis and mechanical stability of tibial pseudarthrosis. In traditional combined surgery, the Williams rod is often used. Long-term intramedullary fixation of the foot and ankle will affect the ankle joint function of children. The intramedullary rod is relatively shorter due to the growth of the distal tibia. In addition, there are some complications such as epiphyseal bone bridge and high-arched foot. The use of a telescopic intramedullary rod may avoid these complications. PURPOSES: To investigate the initial effect of the "telescopic rod" in a combined surgical technique for the treatment of congenital pseudarthrosis of the tibia in children. METHODS: A retrospective study including 15 patients with Crawford type IV CPT who were treated using a combined surgical technique and the telescopic rod from January 2017 to May 2018. The average age at the time of surgery was 43.3 months (16-126 months). Of the 15 patients, 7 had proximal tibia dysplasia and 12 exhibited neurofibromatosis type 1. The combined surgical technique using the telescopic rod included the excision of pseudarthrosis, intramedullary rod insertion, installation of Ilizarov's fixator, tibia-fibular cross union, and wrapping autogenic iliac bone graft. The incidence of refracture, ankle valgus, tibial valgus, and limb length discrepancy (LLD) in patients were investigated. RESULTS: All patients achieved primary union with an average follow-up time of 37.3 months (26-42 months). The mean primary union time was 4.5 months (4.0-5.6 months). Nine cases showed LLD (60%), with an average limb length of 1.1 cm (0.5-2.0 cm). Ankle valgus, proximal tibial valgus, telescopic rod displacement, and epiphyseal plate tethering occurred in 1 case (6.6%) (18°), 3 cases (20%) (10°, 5°, and 6°, respectively), 6 cases (40%), and 2 cases (13%), respectively. There were no refractures during the follow-up periods. CONCLUSION: Although there are complications such as intramedullary rod displacement while using the telescopic rod in a combined surgery, the primary healing rate of congenital pseudarthrosis of the tibia in children is high.

Combined surgery with 3-in-1 osteosynthesis in congenital pseudarthrosis of the tibia with intact fibula.

BACKGROUND: Re-fracture is the most serious complication in congenital pseudarthrosis of the tibia (CPT). There are reports that children with small cross-sectional areas in the sections of the pseudarthrosis are more prone to re-fracture. Presently, preventing complications is a challenge. Increasing the cross-sectional area in healed segments may reduce the incidence of re-fracture. PURPOSE: To elucidate the indications, surgical technique, and outcomes of combined surgery and 3-in-1 osteosynthesis in CPT with intact fibula. METHODS: We retrospectively assessed 17 patients with Crawford Type IV CPT with intact fibula (Type A) who were treated with combined surgical technique and 3-in-1 osteosynthesis between March 2014 and August 2015. The average age of the patients at the time of surgery was 3 years. Incidence of re-fracture, ankle valgus, proximal tibial valgus, and limb length discrepancy (LLD) were investigated over an average follow-up time of 47 months. RESULTS: Primary union was achieved in all patients. The average time for primary union was 4.9 months. Fifteen (88%) cases showed LLD with an average limb length of 1.6 cm; 6 (35%) cases exhibited tibial valgus with an average tibial valgus deformity of 7.8°; 2 cases had ankle valgus, wherein the ankle valgus deformity was 12° in one and 17° in another; and the cross-sectional area of the bone graft was enlarged to 1.74 times that of the tibia shaft. No case had re-fracture during the follow-up period. Movement of the ankle joint was restored in 16 patients with an average dorsiflexion of 22° and an average plantar flexion of 41°; the function of the ankle joint was normal. One patient had plantar flexion of 20° but did not have dorsiflexion. CONCLUSION: Combined surgical technique with 3-in-1 osteosynthesis, which is primarily considered for bone union with a large cross-sectional area, results in a high primary union rate. This can provide satisfactory results in short-term follow-up when treating CPT with intact fibula (Type A).

Combined technique with hydroxyapatite coated intramedullary nails in treatment of anterolateral bowing of congenital pseudarthrosis of tibia.

PURPOSE: The goal of this study is to evaluate the treatment outcomes of anterolateral bowing and residual deformities of distal tibia in patients with CPT using circular external fixation and hydroxyapatite coated flexible intramedullary nailing without excision of affected part of tibia. PATIENTS AND METHODS: Six patients (4 boys and 2 girls, mean age 12.4 ±â€¯4.1 years) were included in the study. Mean follow-up is 2.1 years. In 4 patients with early onset of disease initial surgical treatment (at age of 5-8 years) was dysplastic zone or pseudarthrosis resection with proximal metaphyseal osteotomy for bone transport. Children with unbroken bowed tibia (2 cases of type II according to Crawford classification) had no previous surgery. Neurofibromatosis type I was diagnosed in 4 cases. Surgical technique for residual deformity correction consisted of percutaneous osteotomy, application of circular external frame and composite hydroxyapatite-coated intramedullary nailing. RESULTS: Mean external fixation time was 95.3 ±â€¯17.5 days. All patients never get fractured after frame removal. At the present time, they are considered to be healed, in 2.1 years, in average, without fractures or deformity recurrence. Mean lower limb length discrepancy varied from 2 to 10 mm at the latest follow-up control. After realignment procedure, patients didn't require additional surgery but one. Intramedullary nails were removed in two years after deformity correction for individual reason. CONCLUSION: Correction of anterolateral bowing or residual deformity in children with CPT is indicated. Association of external fixation with intramedullary nailing/rodding left in situ after frame removal ensure stability and accuracy of deformity correction. Biological methods of stimulation of bone formation in dysplastic zone are obligatory to ensure bone union. Intramedullary nailing with composite hydroxyapatite-coated surface provides mechanical and biological advantages in patients with CPT.

Congenital pseudarthrosis of tibia is a genetic, systemic pathology with impaired bone remodeling and unknown pathogenetic mechanisms. Orthopaedic treatment of the disease can fail in some cases. The process of bone remodeling is known to occur under control of local and systemic growth factors, and we sought to explore several osteotropic growth factors, markers of osteogenesis and biologically active molecules in the blood serum of patients with congenital pseudarthrosis of tibia. The study included 12 patients with congenital pseudarthrosis of tibia and anatomical shortening of 2.5±1.1 cm. The' age of patients ranged from 7 years to 18 years. Blood serum was used for enzyme immunoassay analysis. The own blood serum levels of 103 conditionally healthy individuals (of mean age of 13.0±0.27 years) were considered as the norm. Greater changes in the concentration were detected among vascular endothelial and transforming growth factors. The patients showed imbalance in serum TGF, low reparative potential of bone tissue due to osteoclast activation prevailing over differentiation of osteoblasts, progenitor and mesenchymal cells. Dynamics in serum concentration of IGF at the time of frame removal indicated to terminating osteoblast activation and collagen synthesis and concomitant active bone restructuring.

Combination of intramedullary rod, wrapping bone grafting and Ilizarov's fixator for the treatment of Crawford type IV congenital pseudarthrosis of the tibia: mid-term follow up of 56 cases.

BACKGROUND: The purpose of this study was to investigate the initial union rate, refracture rate and residual deformities of congenital pseudarthrosis of the tibia (CPT), using combined surgery including pseudarthrosis resection, intramedullary rodding, autogenous iliac bone grafting and Ilizarov's fixator, with a mean 5.2 years follow-up. METHODS: We retrospectively reviewed the records and diagrams of patients with Crawford type IV congenital pseudarthrosis of the tibia between February 2007 and March 2010. Patients managed by pseudarthrosis resection, intramedullary rod of the tibia, wrapping autogenous iliac bone grafting and Ilizarov's fixator were enrolled. We evaluated the bone union rate, tibial alignment, limb length discrepancy (LLD), valgus deformity of the ankle and the frequencies of refracture during period of follow-up. RESULTS: There were 56 cases enrolled in the study, with a mean follow-up 5.2 years (range, 3 to 6.7 years). The mean age of the patients at surgery was 3.5 years (range, 1.5 to 12.4 years). Fifty (89.2 %) of the 56 patients had primary bone union at site of pseudarthrosis, while 5 obtained union after second surgery and 1 failed. The average time spent to obtain pseudarthrosis initial union was 4.5 months (range, 3.0 to 10.0 months) and mean duration of Ilizarov treatment was 4.7 months (range, 3.2 to 10.4 months). Eleven (19.6 %) patients had proximal tibial valgus with a mean angle of 9.5° (range, 5 to 24°), while 10 (17.9 %) patients had ankle valgus deformities with a mean of 12.3° (range, 6 to 21°). Sixteen (28.6 %) patients had an average 2.2 cm LLD (range, 1.5-4.2 cm). Of the 50 cases who obtained initial bone union of pseudarthrosis, 13 (26.0 %) had refracture which need cast immobilization or secondary surgery. CONCLUSIONS: This combined surgery obtained initial union rate of 89.2 % at primary surgery while the refracture rate is 26.0 %. However, residual deformities such as proximal tibial valgus, LLD and ankle valgus were also existed which should be pay more attention to and dealt with. TRIAL REGISTRATION: This study was registered in ClinicalTrials.gov under the name "The Effect of Combined Surgery in Management of Congenital Pseudarthrosis of Tibia" ( NCT02640040 ), which was released on August 31, 2015.

Burnei's procedure in the treatment of long bone pseudarthrosis in patients having osteogenesis imperfecta or congenital pseudarthrosis of tibia - preliminary report.

RATIONALE: given the recalcitrant behaviour of pseudarthrosis in osteogenesis imperfecta (OI) and congenital pseudarthrosis of the tibia (CPT), there is no ideal solution to treat such challenging deformities. The reconsideration of the already known principles, by using the modern technology, may generate new treatment methods. AIM: the present paper presents the preliminary results of an original reconstruction procedure used to treat large bone defects in paediatric orthopaedics. A case series study, the surgical technique, complications and illustrative cases are presented. METHODS AND RESULTS: 3 cases of pseudarthrosis in OI and 2 cases of CPT were operated by using this technique. The principles of the method are to create an optimal osteoconductive and osteoinductive environment by using a bone autograft, bone allograft and bone graft substitutes and to provide a good stabilisation of the bones. We operated 3 patients with OI and 2 patients with CPT. Four patients had multiple previous surgeries. The follow-up period ranged from 3 to 28 months. Four of the five patients are able to ambulate independently at the moment this paper was written. DISCUSSION: we believe that the present technique could be a reliable alternative to other procedures, especially in cases of repeated failures.

Manejo quirúrgico de la pseudoartrosis congénita de tibia y peroné: experiencia del Hospital Ortopédico Infantil de Caracas / Surgical management of congenital pseudarthrosis of tibia and fibula: experience of the Hospital Ortopédico Infantil de Caracas

El tratamiento de la Pseudoartrosis Congénita de Tibia y Peroné (PCTyP) ha sido diverso. Todas las técnicas de tratamiento tienen una cuota de complicaciones, pero es la re-fractura y la falta de unión las principales consecuencias que se desean evitar. El objetivo de esta investigación se basa en analizar las técnicas quirúrgicas empleadas en nuestro centro y determinar los resultados. Se realizó un estudio retrospectivo, donde se estudiaron 11 pacientes con esta enfermedad con un seguimiento promedio de 4,73 años (DS±4,56). Todos los pacientes en quienes se utilizó la técnica de Charnley-Williams lograron la consolidación, la protección del clavo funcionó hasta que el extremo proximal de la tibia queda desprotegido al crecer el hueso y se produjeron angulaciones en esta zona, usualmente en la tibia proximal. Con el uso del clavo endomedular telescópico de Fassier-Duval se logra la protección de todo el hueso, inclusive durante el crecimiento. Se concluye que la técnica de Charnley-Williams es un buen método para la resolución de esta enfermedad y con el uso del clavo endomedular de Fassier-Duval se evita la refractura y se logra la unión permanente a medida que continúa el crecimiento del hueso. La discrepancia de los miembros inferiores es debido a la afectación de la tibia que compromete su crecimiento normal.

Treatment of Congenital Pseudarthrosis of Tibia and Fibula (PCTyP) has been mixed. All treatment techniques have a share of complications, but is the re-fracture and nonunion of the main consequences are to be avoided. The objective of this research is based on analyzing the surgical techniques used in our center and determine the results. We performed a retrospective study, which studied 11 patients with this disease with a median follow-up of 4.73 years (SD ± 4.56). All patients who used the technique of Charnley-Williams achieved the consolidation, protection of key works until the proximal end of the tibia is unprotected to grow bone and angulation occurred in this area, usually in the proximal tibia. With the use of intramedullary nail-Duval telescopic Fassier protection is achieved across the bone, even during growth. We conclude that the technique of Charnley-Williams is a good way to solve this disease and the use of intramedullary nail-Duval Fassier refracture and prevents the joining is accomplished as bone growth continues. The discrepancy of the lower limbs is due to the involvement of the tibia which assumes normal growth.
